Bad company !!! I have a case against CEF for undue collection, in which I won, but they keep calling me to collect. I already spoke with the representative, Leonel and asked NOT to call me anymore, but the calls continue 2x a day. Anyone who wants to work on it already knows that they will have to work under pressure and earning little because Telemarketing is a lot of exploration.
